Disclosed is a phone case for diving comprising a housing including a rear housing rotatably connected to one side of front housing and sealingly connected to the other side, and a front housing. A surface of rear housing is connected with a photographing window on one side, and is further connected with an air suction assembly located on one side of photographing window and/or a light-filling assembly located on the other side of air suction assembly. The housing, connected with a function button, has a control module connected inside that is in signal connection with function button and light-filling assembly respectively and connected with phone by Bluetooth. Further disclosed is a method for implementing a phone case for diving, wherein air inside housing is extracted by air suction assembly, so that housing is vacuumed inside for good waterproof performance without steam appearing inside housing, making photographing effect better.

A compartmented beverage koozie with a protective compartment that secures personal items while insulating a beverage includes a body defining a cylindrical interior that receives and maintains the temperature of the beverage. A curved plate forms a rigid mounting structure conforming to the cylindrical interior of the koozie. A water-resistant compartment forms an integral structure of the koozie. The water-resistant compartment receives and secures personal items in physical proximity to the koozie, while preventing or substantially reducing exposure of the personal items to water or other environmental effects. A water-resistant compartment pocket holds smaller personal items and a larger compartment for holds larger personal items. A transparent door shows the personal items protected within the water-resistant compartment. A door latch and gasket assembly establishes a water-resistant enclosure. The koozie is a foam structure preserving the thermal state of the beverage within the cylindrical interior. A D-ring permits single-attachment transport.

A water proof sleeve for an electronic device includes an elastic body including an open top and a curved side wall joined to a bottom wall. The curved side wall and bottom wall define an internal cavity receiving an electronic device. A plurality of separated sealing ribs are formed on an internal surface of the side wall. The plurality of sealing ribs are formed circumferentially about the side wall. One of the plurality of sealing ribs is a water sealing rib and includes a radial dimension that is at least twice the size in comparison to the other sealing ribs of the plurality of sealing ribs.

A collapsible vessel reconfigurable between expanded and collapsed configurations. A sleeve combination has an inner sleeve rotatable relative to an outer sleeve. A liner is retained by the sleeve combination. The sleeves have opposed major walls divided by opposed fold line formations. Arrays of flexion apertures span a lateral range from adjacent to the respective fold line formation toward a central portion of the major wall, and an aperture density can vary generally based on distance from the fold line formation to promote a true-round confirmation of the expanded vessel. A lid structure with a disk and opposed retaining tabs can be selectively engaged with the liner, and a retaining strap can be pivotally coupled to the sleeve combination with a first orientation encircling the sleeve combination and a second, longitudinal orientation. A storage bag with first and second longitudinally-disposed stays can receive and further compress the vessel.

Provided is a touch control system of an electronic product in underwater environment. The touch control system includes a sealing device which is configured to accommodate the electronic product. The sealing device includes a sealed chamber interlayer and a sealed shell. Herein the sealed chamber interlayer is opposite to the touch screen of the electronic product and is capable of being pressed and rebounded and is transparent, and the sealed shell is connected with the sealed chamber interlayer in a sealing manner. The sealed chamber interlayer covers a surface of the touch screen completely. The sealed shell covers other surfaces of the electronic product, and implements touch control to the touch screen by applying an external force to the sealed chamber interlayer. Underwater high-accuracy maneuverability of the touch screen of the electronic product may be implemented when an external force is applied to the sealed chamber interlayer by a finger.
